Permanent deformation, stiffness degradation and strength of open hole glass/PA6 UD thermoplastic composite in tension and compression

The permanent deformation, stiffness degradation and strength of UD Glass/PA6 coupons with an open hole under tension and compression loading is investigated. 2 layups: [0/90]5s and [+45/-45]5s were tested. The specimen shape was rectangular with a width of 36 mm and a hole size of 6 mm, according to ASTM D5766. Both monotonic loading as well as Loading-Unloading-Reloading tests were executed. This, together with a measure of the full field strain of the sample (using Digital Image Correlation) allowed to identify the general sample strength as well as identify several regions where permanent deformation and damage occurred.
